Top Medicare Advantage Payers Enroll More Than Two-Thirds of U.S. Market, Eye Further Growth in 2021

The top five Medicare Advantage insurers enroll 67.4% of the national market, according to the latest update to AIS's Directory of Health Plans. Over the past several years, large insurers have rapidly expanded their MA footprints as baby boomers continue to age into Medicare. And most of these payers are focusing on further expansion as the 2021 plan year approaches. Notably, UnitedHealthcare is plotting its largest expansion since 2015, adding 291 counties to its roster. United is currently the top MA insurer in 25 states. CVS Health Corp.'s Aetna is adding 115 new counties to its MA service area for the 2021 plan year, while Humana Inc. will offer HMO products in 125 new counties. Kaiser Permanente's growth has been more restrained, as the company concentrates on its existing regional markets rather than expanding. On average, the top five insurers' MA enrollment increased 11.3% from 2019 to 2020.
